The invention relates to recording machines for time and distancecalculating machines as described in the present specification andillustrated in the accompanying drawings that form part of the same.

Y The invention consists essentiallyl of the novel means employed,whereby the mechanism is operated by the peculiar shape of an instrumentin the form of a card suitable for the calculation of a workmans time,distances, heights, speeds and other uses.

The objects of the invention are to devise a comparatively simple andlsure means of recordlng on a` card or other'like surface the result ofthe measurement of -a card or the like, prepared in a preliminarymachine to act as a tool in the recorder, to eliminate the humanliability to errors in various calculations by effecting the samemechanically, to facilitate the carrying out of the routine in factoriesand other establishments, to enable scientists, travelers andconstructors Ito measure distance, speed and time with accuracyand'despatch and generally to provide an efficient means for thepurpose.

In the drawings, Figure. 1 is a plan viewofthe machine. l

Fig. 2 is a side elevation of the machine. Fig. 3 is a longitudinalsectional' view of the base.

Fig. 4 is a front elevation of the machine. Fig. 5 is a plan view of thebase.

ating rack. e

Fig. 7 is a detail showing the inklng ribbon and shield.

Fig. 8 is a plan view vof the operating'v instrument in the form of a card.v

Fig. 9 is a fragmentary view of a'type ring showinggroups of time andquantity aps- Like numerals of reference indicate corresponding parts ineach figure.

Referring to the drawings, the base 1 is reduced, in width for thegreater part of its length forming the shoulder2, and. adjacent,

to the Ifront end,thc transverse trip recess' 3 extends downwardly andconnects with the channell 4, the latter. terminating in the transversedog recess 5 about midway in the length ofsaidbase 1. ,a

The disks 6 are pivoted near their upper ends 0n the transverse spindle7 extending across the recess 3 and with the pins 8 form trips in theoperation of the mechanismt The said disks 6 at their lower ends arecerf nected to the stops 9 pivotally mounted en the spindle 10 extendingacross thel stop re- -cess 5, said stops gradually increasing in lengthrespectively from-one side of the recess to the other, and each stopbeing conl'nected by a rod 11 to a disk 6. The ,p1ns8 l extend upwardlybeyond' theI surface of the base v1, so that any iiat instrument pushed.along said surface will flatten the pins down wardly thus turning thedisks on their pivot and throwing the stops rearwardly.

The arms '12 project laterally from the base l'slightly forward of thestop recess 5 and at each end carry the spring arms 13, the latterforming shaft sockets 14 at the upper ends. The post 15 projectsupwardly from the upper end of one of the spring arms 15?l and hasattached thereto the The shaft 17 is-secured in the sockets le and onthis shaft the roll 18 is journaled, said roll Abeing formed of the typerings 19, carrying the type 20 separated -by .the pinions21.l

Thev ost 22 projects upwardly from the shaft 1 and isslidably arrangedthereon,

said roll 18 being secured to'said post 22 in such a manner as to avoidbringing the lat# ter with said roll in rotation. Y

The spring 16 is secured to the post y22 and is always in tension,consequently the roll will always have the tendency to slide to ward thefixed post 15. The type rings A19 are 'of diiierent diameters so thatthe dilferent lengths of the stops will reach correspondingly or fail toreach, as the case may be.

termediately The roll 18 is mounted on the shaft 17, so that the spring23 brings the roll normally back to Zero as far as the typeareconcerned, consequently a pawl 24 is springheld to one or other of thepinions 2 1 during operation and is thrown back during the turning andtransverse movements of said lroll by the contact of the pivoted rackbearing' 25 with the arm 26 in engagement with said pawl.

The rack bearing 25 is in the form of a sleeve having the lug 25pivotally secured by the pin 27 to the side of the base 1 1nof thedistance between the front end and shoulder 2, said sleeve beingnormally held in an inclined position by the spring 28 secured to saidbase.

The rack 29 slides in the bearing 25 and at its front end has the thumbknob 30.

Toward its rear end the rack has a groove 31, which registers with therib 32 on the bracket 33 extending upwardly from the base 1, said ribterminating before it reaches the base, so that the rack is free in itshorizontal position and locked in its inclined position. The said rackwhen brought to its horizontal position meshes with one or other of thesaid pinions, and in drawing it forward the roll 18 is rotated to theextent of lals shoulder the travel of said'rack.

The permanent the base at the front end, and its front face is levelwith the front end of said rack when the latter is in its zero position,which corresponds with the zero position of the roll 18.

lThe card 35 is the instrument or tool for operating the machine and atthe same time for receiving the record in time and quantty as the typeon the type rings of the roll 18 are arranged preferably in charactersin groups, one set 41' of each group denoting the time elapsed and theother 42 denoting the value of the time or other quantity, and

' while the time type are in horizontal alinement and correspond on theseveral type rings, the quantity type represent different rates orcalculations on each ring, therefore though in the rotation of the rollthe time type on each roll will correspond, the particular ring over thebase will show the rate for that time, that is wanted for the record.

The card 35 is previously prepared by another device and is here shownas clipped at each side, the strips taken away being dierent lengths andconsequently leaving shoulders 36 and 37 at diiierent depths in thecard, and it is the distance between these depths that determines thetime, for in its use the card is inserted under the roll 18, oneshoulder 36 being against the permanent stop 34, while the rack is drawnup to the 37, until its outer end abuts said shoulder, then the roll 18is .turned the proper distance to bring around for printstop 34 standsup from' ing purposes the time type corresponding to the distancelongitudinally between the shoulders 36 and 37. .l y

The rate or quantity is determined by the longitudinal slot 38 in thecard, as said slot forms a path for one of the trip pins 8, thus leavinga stop 9 undisturbed, and this particular stop reaches forward just farenough to stop a type ring over the base in printing position behind theo ening in the ribbon shield 39, the latter s ielding the adjacent typefrom also printing through the ribbon 40.

Briefly the purpose and operation may be further explained The card isfirst clipped on one side and then on the other at a later hour inanother machine or in any suitable way, and the joining piece near theouter end of the slot 38 torn away` to leave a free passage for one ofthe pins, said slots 38 being arranged at that part of the cardcorresponding to the particular type ring, that is to say, there arediiierent cards for different rates, and where the machine isused infactories, the rate of charge for the job is first determined and thatparticular card given to the workman.

The slot is of course only one way of fixing the card for an escapementmechanism and it must be understood that any construction in laterallydriving, rotating or stopping the roll may be used so long as it iswithin the scope of the claim for novelty following and of course 'thecard will be made to correspond to the machine.

Therack on being drawn up tothe shoulder 37 turns the roll 18 and at thesame time tion for printing. rI`he roll which is very near the card isthen pressed down by the yielding of the spring arms 13 on to the cardand the time and rate printed. The rack is then moved back to its zeroposition, and consequently the roll also returns to its zero position,in readiness for the next operation.

This application accompanies a separate application for a card 'filedunder Serial Number 79,451.
